Most of the transition metals exhibit (i) paramagnetic behaviour (ii) diamagnetic behaviour (iii) variable oxidation states (iv) formation of coloured ions
Options
- A(ii), (iii) and (iv)
- B(i), (iii) and (iv)
- C(i), (ii) and (iii)
- D(i), (ii) and (iv)
Correct answer
B. (i), (iii) and (iv)
Step-by-step solution
Due to presence of unpaired electrons in n - 1 d orbitals, the most of the transition metal ions and their compounds are paramagnetic. They form coloured ions and show variable oxidation states also due to presence of vacant d-orbitals.
